Detailed Description
defines cell interface
In VTK, spatial-temporal data is defined in terms of a dataset which is composed of cells. The cells are topological entities over which an interpolation field is applied. Cells are defined in terms of a topology (e.g., vertices, lines, triangles, polygons, tetrahedra, etc.), points that instantiate the geometry of the cells, and interpolation fields (in the general case one interpolation field is for geometry, the other is for attribute data associated with the cell).
Currently most algorithms in VTK use vtkCell and vtkDataSet, which make assumptions about the nature of datasets, cells, and attributes. In particular, this abstraction assumes that cell interpolation functions are linear, or products of linear functions. Further, VTK implements most of the interpolation functions. This implementation starts breaking down as the complexity of the interpolation (or basis) functions increases.
vtkGenericAdaptorCell addresses these issues by providing more general abstraction for cells. It also adopts modern C++ practices including using iterators. The vtkGenericAdaptorCell is designed to fit within the adaptor framework; meaning that it is meant to adapt VTK to external simulation systems (see the GenericFiltering/README.html).
Please note that most cells are defined in terms of other cells (the boundary cells). They are also defined in terms of points, which are not the same as vertices (vertices are a 0-D cell; points represent a position in space).
Another important concept is the notion of DOFNodes. These concept supports cell types with complex interpolation functions. For example, higher-order p-method finite elements may have different functions on each of their topological features (edges, faces, region). The coefficients of these polynomial functions are associated with DOFNodes. (There is a single DOFNode for each topological feature.) Note that from this perspective, points are used to establish the topological form of the cell; mid-side nodes and such are considered DOFNodes.

Generate a contour (contouring primitives) for each `values' or with respect to an implicit function `f'. Contouring is performed on the scalar attribute (`attributes->GetActiveAttribute()' `attributes->GetActiveComponent()'). Contouring interpolates the `attributes->GetNumberOfattributesToInterpolate()' attributes `attributes->GetAttributesToInterpolate()'. The `locator', `verts', `lines', `polys', `outPd' and `outCd' are cumulative data arrays over cell iterations: they store the result of each call to Contour(): - `locator' is a points list that merges points as they are inserted (i.e., prevents duplicates). - `verts' is an array of generated vertices - `lines' is an array of generated lines - `polys' is an array of generated polygons - `outPd' is an array of interpolated point data along the edge (if not-NULL) - `outCd' is an array of copied cell data of the current cell (if not-NULL) `internalPd', `secondaryPd' and `secondaryCd' are initialized by the filter that call it from `attributes'. - `internalPd' stores the result of the tessellation pass: the higher-order cell is tessellated into linear sub-cells. - `secondaryPd' and `secondaryCd' are used internally as inputs to the Contour() method on linear sub-cells. Note: the CopyAllocate() method must be invoked on both `outPd' and `outCd', from `secondaryPd' and `secondaryCd'. NOTE: `vtkGenericAttributeCollection *attributes' will be replaced by a `vtkInformation'.

Cut (or clip) the current cell with respect to the contour defined by the `value' or the implicit function `f' of the scalar attribute (`attributes->GetActiveAttribute()',`attributes->GetActiveComponent()'). If `f' exists, `value' is not used. The output is the part of the current cell which is inside the contour. The output is a set of zero, one or more cells of the same topological dimension as the current cell. Normally, cell points whose scalar value is greater than "value" are considered inside. If `insideOut' is on, this is reversed. Clipping interpolates the `attributes->GetNumberOfattributesToInterpolate()' attributes `attributes->GetAttributesToInterpolate()'. `locator', `connectivity', `outPd' and `outCd' are cumulative data arrays over cell iterations: they store the result of each call to Clip(): - `locator' is a points list that merges points as they are inserted (i.e., prevents duplicates). - `connectivity' is an array of generated cells - `outPd' is an array of interpolated point data along the edge (if not-NULL) - `outCd' is an array of copied cell data of the current cell (if not-NULL) `internalPd', `secondaryPd' and `secondaryCd' are initialized by the filter that call it from `attributes'. - `internalPd' stores the result of the tessellation pass: the higher-order cell is tessellated into linear sub-cells. - `secondaryPd' and `secondaryCd' are used internally as inputs to the Clip() method on linear sub-cells. Note: the CopyAllocate() method must be invoked on both `outPd' and `outCd', from `secondaryPd' and `secondaryCd'. NOTE: `vtkGenericAttributeCollection *attributes' will be replaced by a `vtkInformation'.

Is there an intersection between the current cell and the ray (`p1',`p2') according to a tolerance `tol'? If true, `x' is the global intersection, `t' is the parametric coordinate for the line, `pcoords' are the parametric coordinates for cell. `subId' is the sub-cell where the intersection occurs.

- Postcondition
- valid_result: (result>=0) && (IsPrimary() implies result==0)
Implemented in vtkBridgeCell.
Return the distance of the parametric coordinate `pcoords' to the current cell. If inside the cell, a distance of zero is returned. This is used during picking to get the correct cell picked. (The tolerance will occasionally allow cells to be picked who are not really intersected "inside" the cell.)
- Postcondition

Implemented in vtkBridgeCell.

pure virtual |
Return a contiguous array of parametric coordinates of the corrner points defining the current cell. In other words, (px,py,pz, px,py,pz, etc..) The coordinates are ordered consistent with the definition of the point ordering for the cell. Note that 3D parametric coordinates are returned no matter what the topological dimension of the cell.

Tessellate the cell if it is not linear or if at least one attribute of `attributes' is not linear. The output are linear cells of the same dimension than the cell. If the cell is linear and all attributes are linear, the output is just a copy of the current cell. `points', `cellArray', `pd' and `cd' are cumulative output data arrays over cell iterations: they store the result of each call to Tessellate(). `internalPd' is initialized by the calling filter and stores the result of the tessellation. If it is not null, `types' is filled with the types of the linear cells. `types' is null when it is called from vtkGenericGeometryFilter and not null when it is called from vtkGenericDatasetTessellator.
